Self-Consolidation Mechanism of Nanostructured Ti₅Si₃ Compact Induced by Electrical Discharge

Figure 4

SEM micrographs of the cross-sections of consolidated Ti₅Si₃ compacts obtained by (a) hot-pressing at 1200°C in a vacuum of 2 × 10⁻⁶ torr for two hours with a pressure of 10 tons and electrical discharge consolidation using (b) 7.0 kJ and (c) 8.0 kJ of input energy.
